Good that you're getting at least 1 Digital Thermometer with a Probe, because his Basking Spot Surface Temperature needs to be between 105-110 degrees F in order for him to properly digest his food, and this will also effect his appetite and energy levels if it's too low, and you cannot measure the Basking Spot Surface Temperature with any type of stick-on thermometer, it must be a Probe or a Gun.
I don't know what a "Standard" tank set-up means, as it seems no one has the same idea when they first come to this forum, lol. What I can tell you is that your 5% UVB tube, even though it's a T5 strength tube, must be strapped to the underside of any mesh lid to the tank, and it must be within at least 6-7" of his basking spot/platform, and it also must be replaced once every 6 months...This is because it's only a 5% UVB output tube, thus it cannot be blocked by a mesh lid (you lose 40% of the
UVB light to the mesh), and it cannot be any further away than 6-7" from your Dragon, and it will stop emitting any
UVB light at about 6 months old. So if it's a tube/fixture that you got from the previous owner, I highly suggest getting him a new one...Actually, I highly suggest you get him a new one immediately anyway, and it needs to be at least a 10% tube.
I don't know what length your T5 tube fixture is, but you can cheaply order the Reptisun 10.0 T5HO UVB tubes on Amazon.com and they will be fine in the T5 fixture you already have the 5.0 in. If your fixture is a 24" fixture, then you can order a 22" Reptisun 10.0 T5HO UVB tube on Amazon.com for about $25 or less shipped...if it's a 36" fixture then you would need the 34" 10.0 T5HO, if it's an 18" fixture then you'd need the 16" 10.0 T5HO...
The difference between the 5.0 and the 10.0 is that the 10.0 is a 10% UVB output tube, which is what is needed by all desert reptiles anyway...The 10% or 10.0 tube puts out TWICE the
UVB light that the 5.0 tube does. So basically you have to treat a 5.0 or 5% T5 strength tube just like you would treat a 10.0 T8 strength tube, the strength of the tube has nothing to due with the UVB output. So if you upgrade to a 10.0 T5HO tube #1) It can sit on top of the mesh lid, #2) It only needs to be within at least 10-11" of his basking spot, and #3) It only needs to be replace ONCE EVERY 12 MONTHS, so you save a lot of money over time , in addition to it being much better for your Dragon.
*****For the time being, be sure to use zip ties, wire, twine, etc., weave them through the mesh lid, and then strap the entire tube fixture to the underside of the mesh lid. Be sure that you strap it so that it's over the Hot Side of the tank, leaving rood for the bright-white colored Basking Bulb to sit on top of the mesh and RIGHT ALONGSIDE the UVB tube, so that BOTH LIGHTS ARE SHARING THE TOP OF THE HOT SIDE OF THE TANK...Then position his basking spot/platform directly underneath both lights so that he gets both lights while basking.
****BE SURE TO SET BOTH THE LIGHTS UP OVER THE HOT SIDE OF THE TANK AND PUT THE BASKING PLATFORM/SPOT UNDERNEATH BOTH LIGHTS, THEN LEAVE THEM BOTH ON FOR AT LEAST 30 MINUTES BEFORE PUTTING THE PROBE OF THE DIGITAL THERMOMETER RIGHT ON THE BASKING SPOT/PLATFORM TO MEASURE THE BASKING SPOT SURFACE TEMPERATURE!!! Be sure to also allow the Probe to sit on each spot you measure for at least 20 minutes or until the numbers stop rising before you read the temperature...
Calciworms are also called Black Soldier Fly Larva (BSFL)/Phoenix Worms/ReptiWorms/NutriGrubs...they are all the same thing, just different brand names. They are an excellent live feeder insect for Dragons, high in healthy protein, very high in Calcium (YOU STILL HAVE TO DUST THEM IN CALCIUM POWDER 5 DAYS A WEEK, REGARDLESS OF WHAT THE VENDOR SAYS), very low in fat, and very high in water...
***If you have a local pet shop that sells large BSFL in bulk or cheaply that's great, I wish I did. However, usually people only have places like Petco and Petsmart, and Petsmart doesn't sell them at all, and Petco sells a container of 25 Calciworms for a ridiculous $4.25, they are all different sizes, most of them are tiny, and most are usually dead. It's a total rip-off. So if you're going to make BSFL your daily live insect, which is a very good choice (I've been using them as my main live feeder for about 10 years now with nothing but great results), then I highly suggest that you order them in bulk online. I buy from 2 different places, the cheapest one that I mainly use is
www.dubiaroaches.com and I buy 1,000 size large per month for about $25 shipped...you can see the rip-off at Petco, lol. You can actually feed your young baby size larges because they are soft-bodied worms, that's another advantage to them, you don't need to feed smalls or mediums, just order the larges. The other place is
www.symtonbsf.com which has similar prices, just a little higher shipping.
DO NOT PUT THE CALCIWORMS/BSFL IN THE FRIDGE, THEY'LL DIE!!!!! You can keep them in temps down to about 45-50 degrees F and they'll go dormant, but no colder than that. They are not like wax worms, mealworms, etc. that you can just keep in the fridge, pull them out and they'll wake up (which is exactly why most are dead when you buy them at Petco). If you have a basement, a garage, even a covered balcony/deck/patio that you can keep them on that's the best way to do it. I keep my bulk BSFL worms in a medium size plastic tub with a lid that I bought at Walmart for like $7. You can use either Oat Bran or just regular old plain Oat Meal to keep them in. So I just buy 2 canisters of Quaker Oats and dump them in the plastic tub as their bedding, then I just dump the bulk BSFL in (I actually use 2 containers because I'm buying 1,000 at a time, if you only have one Dragon and only order 500 or less a month then you can use one container). Then each morning you can Gut-Load them with the same fresh greens and veggies that you give to your Dragon. Just throw a good size handful of the fresh greens/veggies into the container and that will keep them fed and
hydrated. i keep mine in my basement where it's around 50-55 degrees, so they go pretty dormant. Then I just go down there with a smaller container, get the number of worms that I need, bring them upstairs and run them under luke-warm water to totally wake them up and get them moving. Then I dust them and feed them..
****Be sure that your Dragon gets a Calcium powder 5 times a week and a Reptile Multivitamin powder 2-3 times a week.
He's most likely going through Relocation Stress right now, it can last up to a week or so, but if you don't have that 5.0 UVB tube strapped to the underside of the mesh lid and within about 6-7" of his basking spot/platform, and you don't have his temperature zones within the correct ranges, specifically his Basking Spot Surface Temperature (between 105-110) and his Cool Side Air/Ambient Temperature (between 75-80 degrees maximum) these things will greatly effect his appetite and energy levels, specifically the
UVB light.
Also, be sure to leave both his UVB tube and his bright-white colored Basking Bulb on every single day for at least 13-14 hours.
